CVE-2026-12775Public exploitNetwork attack vector

Unauthenticated SQL injection via raw username query

Published Jun 21, 2026 · Updated Jun 21, 2026

SQL injection in Montodel House-Rental-Management at commit 90010017b81265eb1ef3810268909f7719a33863 allows remote attackers to alter login queries. The login form posts to ajax.php?action=login, where Action::login extracts POST values and concatenates username directly into a SELECT statement without parameter binding. No authentication is required; the crafted time-delay payload provides a blind database oracle, and altered predicates can bypass the login check.
